UNITED STATES SAMUEL R. KING, OF GLENBROOK, CONNECTICUT.

CA1 STOPPER.

Application filed March 30, 1923. Serial No. 628,856.

To all whom it may concern:

Be it known that I, SAMUEL KING, a citizen of the United States, residing at Glenbrook, county of Fairfield, State of Connecticut, have invented a new and useful Cap Stopper, of which the following is a specification.

This invention .relates to closures for bottles and the like, and has for an object to provide an improved closure which may be. quickly and easily applied, which will be absolutely tight and thus not leak, which will not be acted upon by alkalies, and which may be used as a temporary closure after the bottle has once been opened.

Vith the foregoing and other objects in view I have devised the closure illustrated in the accompanying drawing, in which Fig. 1 is a side view of the upper portion of the bottle showing my closure in place thereon, the upper end of the bottle and the closure being shown in section.

Fig. 2 is a side elevation showing one form of cap and securing means for fastening it to the bottle neck which may be used with my improved closure.

Fig. 3 is a plan view of the closure disk before being applied to the bottle.

Fig. 4 is an edge view thereof.

Fig. 5 is a bottom plan view of the disk after it has once been applied to and removed from the bottle.

Fig. 6 is an edge view thereof.

Fig. 7 is a top plan view of a spring disk which may be employed, and

Fig. 8 is a transverse section through the same.

Numeral 10 represents the body of the bottle having the usual neck 11 provided with lugs 12 on the outer wall thereof adapted to engage the inturned flanges 13 of a metal cap 14 to secure the same over the open end of the bottle neck, and these flanges may be provided with upwardly curved portions 15 to engage the under sides of lugs 12 to clamp the cap down on the end of the bottle neck. This specific type of cap and means for clamping the same to the end of the bottle neck is merely illustrative as other forms of caps and securing means may be employed if desired.

Enclosed within the cap, and held tightly cap, is my improved closure 16. This closure comprises a soft fibre disk, preferably of thick and heavy canton flannel saturated with a mixture of beeswax and paraffin. The preferred mixture is composed of approximately twenty percent beeswax and approximately eighty percent paraffin. For the particular purpose for which this closure has been used approximately this portion of wax and paraflin has been found to be the most satisfactory, but the proportions may be varied if desired, and I may use from five percent to seventy five percent beeswax and the remainder of paraffin. The preferred mixture will soften or become plastic at about 120 F., but will be solid at ordinary temperatures. In sealing the bottle the disk is applied to the ends of the neck thereof while it is at a suiiiciently high temperature to be softened, and as the flannel is also soft, when the disk is pressed against the end of the bottle neck this neck will set into it, as indicated in Fig. 1, and make an absolutely tight closure which will not leak. It is extremely useful for certain proprietary medicines as it is not acted on by alkalies. As the disk cools after being applied to the bottle neck it becomes solid.

It will also make a very good temporary closure after the bottle has once been opened, as the end of the neck will seat into the annular groove 17 which was formed when the softened disk was pressed against the end of the bottle neck.

I prefer to place between the saturated flannel disk and the metal cap a spring which will react between the same to press the disk against the end of the bottle neck, and prefer to use the type shown in the drawing, that is, a sheet metal disk 18, bulged at its center, as shown at 19, to press against the bottom of the cap. But this spring disk is not necessary as screw threads or other cam acting means may be employed for connecting the cap to the bottle, and which will press the disk tightly against the bottle neck.

The closure as above described makes a very tight and efficient sealing means for the bottle Which may be easily and quickly applied and Which will not be reacted upon thick fibre disk saturated with a mixture by alkalies. It will also make a very effiof approximately twenty percent beeswax 1 cient temporary closure after the bottle has n eighty percent pal afiin.

5 once been opened. In testimony whereof I affix my signature.

Having thus set forth the nature of my 111- Vention, What I claim is: SAMUEL R. KING.

A bottle closure comprising a relatively
